摘要

摘要: 为了提高页岩气水平井固井质量,满足分段压裂需求,对彭水地区海相页岩气水平井固井技术进行了研究。针对彭页HF-1井固井技术难点,开展了以通井数据为基础的水平井套管下入数值模拟分析,优选了扶正器类型和扶正器安放间距, 针对该井部分井段地层漏失特性,采用"应力笼"理论开展承压堵漏作业,并优选合适的高效驱油冲洗液和隔离液及水泥浆,满足界面润湿反转和驱油要求。通过数值模拟分析,设计的弹性水泥浆弹性模量6.5~8.5 GPa,扶正器端面居中度达到67%,水平段固井质量能够满足压裂的需求。CBL测井结果表明,彭页HF-1井水平段固井优良率78.4%,质量合格,压裂过程未发现层间窜现象。该技术对海相页岩气井固井有一定的借鉴意义,但需要进一步研究其适应性。

Abstract: In order to improve the shale gas well cementing quality and meet the demand of multi-stage fracturing,studies on marine shale gas horizontal well cementing in Pengshui Area were carried out.Based on cementing difficulties for Pengye HF-1 well,we carried out horizontal well casing data simulation analysis based on the tripping data,optimized the stabilizer type and placement space,conducted pressure sealing using the "stress cage" theory to overcome the lost circulation in this section as well as optimized mud flusher and spacer,to meet interface wettability reversal and flushing requirements.Field data showed that,through the numerical simulation analysis and by designing the elastic modulus of elasticity cement slurry to 6.5-8.5 GPa,the end centralization of centralizer reached 67%,which could effectively guarantee the cementing quality and meet the demands of fracturing.CBL logging data showed the acceptance rate of cementing in horizontal section of Pengye HF-1 Well was 78.4%,in line with quality standard,and no interlayer channeling occurred during the fracturing.The research showed that,the technique had guiding significance to cementing in marine shale formation,but adaptability of the technique must be studied further.
